To all whom it may concern:

Be it known that I, ANDREW RATHBONE, a subject of the King of England, residing at Warrington, in the county of Lancaster, England, have invented new and useful Improvements in Wire-Drawing Machinery, of which the following is a specification.

This invention has reference to continuous wire drawing machinery, and more particularly to that type where the wire is drawn over multiple pulleys mounted on vertical spindles; and the chief object of the present invention, in addition to that of providing a machine which will give a large output, and occupy small space, is that of being able to utilize, largely, existing machinery for wire drawing, or to reduce the cost of new machinery; that is, to simplify the making, and also the working of such machines.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the a paratus; and Fig. 2 is a plan of same; wh1 e Figs. 3 and 4 are views showing details.

Referring now to the drawings, the driving block cone a, which is of the multiple pulley or roove type, has grooved pulley portions of diflerent diameters, divided by anges, they being of successively smaller diameter from the top to the bottom; and they are supported upon a s indle I), which is normally revolved, anc extends up through a bottom bearing 0, set on the draw bench or table aZ of the machine.

Upon the upper end of the block a, there is a cylindrical drum f, upon which the wire is wound. The bench d has a flange at e at each side to retain and convey away the water or other liquid which may pass down into it from the blocks and wire. Behind this draw bench or table 0? there is a trough or vessel 9 containing lubricating liquid for wet-drawing, and in which the reel or swift h containing the wire to be drawn, is disposed and runs; being disposed preferably on the right-hand side of the block which is taking wire from it.

Immediately behind the block a, there is placed a coned multiple pulley, or cone 2', adapted to revolve idly on a spindle 7' carried from an arm or support is. Connected with this arm is a hand lever Z which serves to move or operate it for moving the cone '5. The arm and lever are hinged and mounted on a base block m, fixed on the bench or table 6 of the machine.

The lever Z has connected with it-preferably formed in one with ita guide bar n, with gaps in its edges, leading into holes, and through which the wires pass; and these serve as guides, and the bar n forms part of the lever Z, see detail Fig. 3.

The drawing dies ;0 are disposed between a notched guide bar 9, provided with gaps and recesses similar to those marked 0 in the bar n of the lever Z, and the upstanding horns 'l'; and this guide bar q, and also the guide bar n, are set at an inclination to correspond with the inclination of the conical pulley a, and pulley a, so that the wires extending between the pulleys i and a would be in a line as far as possible, see detail Fig. 4.

The lever Z is hinged at Z in the base m, and works between two stops 8 on a plate 8, formed and standin on the base m; and the lever Z will be held 1n the osition to which it has been moved, by a pm 15, which passes through holes 8 in the plate .9, and stands behind or in front of the lever Z after it is actuated.

The portions 0. and f of the block is cast in one, the lower part being hollow and provided with a central upstanding boss a which extends or rises nearly to the top of the cone; and the space within the cone, be tween the boss and the outer part, is kept full of water or liquid, by supplying it in a constant stream into the top of the drum 7, the surplus overflowing the top of the boss a, and passing through the space between it and the shaft, out onto the tray of the table or bench aZ, whence it is suitabl conducted away. By this means, the whee s as well as the wire are kept cool.

When the piece of wire to be drawn is to be passed over the pulleys, and through the dies, the arm 70 will be raised up by pulling the lever Z back, which raises the pulley 2' out of the bath of liquid; and When the wire has been guided around the various grooves of the pulleys 'Z and a, through the dies p, and the guides g and n, in a continuous manner,

the block and apparatus are started; and then the pulley i is moved downward into the liquid in g by gradually pressing the lever Z away, and when it is submerged, or practically submerged, the lever Z and arm is, and pulley 2' are held in this position by in serting the pin 2? through the hole s so-holding these parts in position. The wire is generally passed several times around each of the pulley portions of the multiple pulley a; and the wire is first passed through the lowest die, and over the smallest grooves of the pulley.

It will be understood that a plurality of blocks a and 2', guide plates 1% and 1", and dies 0 may be employed in Connection with one bath g; also that the machine described above is serviceable for dry-drawing as well as wet-drawing.
